We need to converge the networks ! Who will drive the convergence? Bellheads versus Netheads Information and Communications http: //www. siemens. com/mobile-business

The „Prejudices“ • Freaks • Chaotic • No understanding of carrier business Bellheads Netheads • • Bureaucratic Inflexible monopolies No customer focus Old technology Information and Communications http: //www. siemens. com/mobile-business

The Battlefield: Convergence Packet-Switched Circuit-Switched • Flexibility • Best-effort • Availability • Reliability • Guaranteed Service Optimized for Data Netheads Information and Communications http: //www. siemens. com/mobile-business Optimized for Voice Next Generation Networks Bellheads

Evolving the network 1 st Alternative ? Only upgrade in voice sector Consequences: • No new converged services • No synergy between networks • No offering of Vo. IP/ATM services Information and Communications http: //www. siemens. com/mobile-business

Evolving the network 1 st Alternative ? Your competitors will win! Information and Communications http: //www. siemens. com/mobile-business

Evolving the network 2 nd Alternative ? Build one new universal network (IP or ATM) Consequences: • Implement all existing services again in IP or ATM • Very long time to market (before system is stable) • Interworking with legacy tremendously costly • High investment necessary Information and Communications http: //www. siemens. com/mobile-business

Evolving the network 2 nd Alternative ? “Engineer’s dream” Information and Communications http: //www. siemens. com/mobile-business
